JESSE E. MCROBERTS, OF WOONSOCKET, SOUTH DAKOTA.

ASH-PAN CLEANER.

I To all whom it may concern:

' Be it known that I, Jnssn E. MoRoBERTs, a citizen of the United Statesof America,

elevation of the same. longitud nal sectlonal view of the same.

residing at lVoonsocket, in the county of Sanborn and State of SouthDakota, have invented new and useful Improvements in Ash-Pan Cleaners,of which the following is a specification.

- This invention is an improved ash pan cleaner forthe ash pans oflocomotive and other steam boiler furnaces, to enable the same to bereadily cleaned without the necessity of getting under the same, and thesaid invention consists in the construction, combination and arrangementof devices herein after described and claimed.

In the accompanyingdrawings, Figure 1 1s a horizontal sectional v1ew ofa boiler furnace ash pan prov ded with a cleanmg mechanism embodying myimprovements. Fig. 2 1s a vertlcal transverse sectlonal view of the sametaken on the plane indicated by the line 2-2 of Fig. 1. Fig. 3 is a sideFig. l is a vertical Figs. 5 and 6 are detail perspective views of thechain links to which the ends of the flight bars are connected.

The ash -pan 1, which may be of the construction here shown or of anysuitable construction, is provided with a bottom plate 2 andwithupwardly opening hinged end doors 3 whiohmay be ra1sed or lowered atwillQ: Secured to the side walls of the said side portions of the bottomplate.

ash Ipan, at a suitable distance from the angle irons 5.

At the ends of the ash pan, below the bottom thereof, are downwardlyextending brackets 6 which are provided with bearings 7 for shafts 8;Each ofthe said shafts is provided near its ends with sprocket wheels 9.'One of the said shafts is further provided at one end -with a worm gear10. Brackets 11 are secured to the outer side of the side walls of thepan and depend therefrom to a suitable distance below the bottom plate2, said brackets supporting a pair of longitudinally disposed shoe bars12. On I oneside of theash pan, at one of the lower corners thereof, issecured a plate 13 which Specification of Letters Patent.

is provided with bearings 14 for an inclined shaft 15. Said shaft has ahandle or lever 16 at its outer end whereby it may be rotated and isprovided near its inner end with a worm 17 which engages the gear sothat when the said shaft is turned, the shaft 8, which is gearedthereto, is also rotated.

The sprocket wheels 9 of the respective shafts 8 are connected byendless chains 18. The upper leads of the said chains extendlongitudinally of the ash pan and bear on the bottom. plate thereofunder the shoe bars 4-. The lower leads of such chains travel upon theshoe bars 12. The said chains are connected together by transverselydisposed flight bars 19. Each of the said flight bars has its endssecured to brackets 20 with which certain of the links of the chains areprovided. The said chains are preferably of the usual detachable linkconstruction so that any suitable number of the flight bars may beconnected thereto and the said flight bars may be disposed at anydesired distance apart.

The operation of my invention is as follows: Ordinarily the doors areclosed. When it is desired to discharge ashes from the bottom plate ofthe ash pan, such doors are first opened to a suitable extent to permitthe flight bars of the endless chains to pass under them, the shaft 15is then turned so as to impart motion to the shafts 8 and flight bars,and as the latter move on the bottom plate, they serve to carry theashes therefrom and to discharge the ashes from one end of the ash pan.The shoe bars 4 bear on the flight bars of the upper leads of the chainsand keep such flight bars in contact with the upper surface of thebottom plate and are prevented from passing over the ashes.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is An ash pan of the class described having abottom plate, side walls and end doors, shafts disposed transversely ofthe ash pan and having bearings under the ends thereof, such bearingsbeing secured to and carried by the bottom plate, such shafts havingsprocket wheels and one of such shafts also having a gear wheel, endlesschains connecting such sprocket wheels, having their upper leadsdisposed to travel lengthwise on the upper side of the bottom plate ofthe ash pan and their lower leads below such hot tom plate, flightelements connecting the from the sides of the ash pan and shoe barsendless chains, a worm shaft having the 1 attached to said brackets,disposed on the worm thereof disposed in engagement With lower leads ofsaid chains. such gear Wheel and having its bearings se- .ln testimonywhereof, I atfix my signature 5 cured directly to one of such sideWalls, I in presence of two Witnesses.
